摘要: 为了解不同品种北美海棠耐盐性,以天津市远大园林苗圃提供的北美海棠‘冬红’、‘舞美’、‘亚当’、‘喜洋洋’、‘绚丽’、‘凯尔斯’、‘王族’、‘红宝石’8个品种为试材,测量了植株8项生长指标。结果显示:‘冬红’基径最大(2.740 cm),‘王族’最小(2.065 cm);‘红宝石’胸径最大(2.445 cm),‘王族’最小(1.895 cm);‘冬红’株高最大(461 cm);‘凯尔斯’冠幅最大(344.200 cm),‘舞美’最小(122.450 cm);‘舞美’一年生枝最长(54.933 cm),‘红宝石’则最小(30.400 cm);‘亚当’一年生枝数量最多(14.200个),‘王族’最少(6.400个);‘舞美’叶片数量最多(46.067个),‘红宝石’最少(11.133个);‘冬红’年轮年均生长量最大(0.633 cm),‘王族’最小(0.464 cm)。隶属函数综合分析显示,8种海棠的耐盐碱性排序为‘冬红’和‘凯尔斯’>‘亚当’、‘红宝石’和‘绚丽’>‘喜洋洋’和‘舞美’>‘王族’。

Abstract: In order to compare the adaptability of salinity of Malus micromalus cv., the growth characteristics of 'Dong Hong', 'Wu Mei, 'Ya Dang', 'Xi Yangyang', 'Xuan Li', 'Kai ersi', 'Wang Zu', and 'Hong Baoshi' were researched in the nursery of Yuan Da landscape company in Tianjin. The results showed that the stem diameter of 'Dong Hong' at base was largest(2.740 cm)and 'Wang Zu'(2.065 cm)was the smallest . The diameter of 'Hong Baoshi' at 1.2 m height of stem was the largest(2.445 cm), and 'Wang Zu'(1.895 cm)was the smallest. The plant of 'Dong Hong' was the hightest(46l cm)and the canopy of 'Kai Ersi' was the widest(344.200 cm), and one of 'Wu Mei'(122.450 cm)was the narrowest. The annual branch of 'Wu Mei' was longest(54.933 m), and one of 'Hong Baoshi'(30.400 cm)was the shortest . The annual branch of 'Ya Dang' was most(14.200), and one of 'Wang Zu'(6.400)was the least . The leaves of 'Wu mei' was most(46.067), and one of 'Hong Baoshi'(11.133)was the least . The average growth rings of in 'Dong Hong at stem was the widest(0.633 cm), and one of 'Wang Zu'(0.464 cm)was the narrowest. The salt tolerance of the eight varieties was 'Dong Hong' and 'Kai Ersi'>'Ya Dang', 'Hong Baoshi' and 'Xuan Li'>'Xi Yangyang' and 'Wu Mei'>'Wang Zu' by the comprehensive membership function analysis.
